Question

Which of the following groups of cells in the male gonad represent haploid cells?
A) Spermatogonial cells
B) Germinal epithelial cells
C) Secondary spermatocytes
D) Primary spermatocytes

Answer 1

Hint: Secondary spermatocytes are haploid (N) cells with half as many chromosomes as primary spermatocytes. Males in all species, including hermaphrodites like C. elegans, which may exist as either a male or a hermaphrodite, generate spermatocytes.

Complete Step by Step Answer:
The secondary spermatocyte that is created from a primary spermatocyte by the first meiotic division; the second meiotic division creates two spermatids from each secondary spermatocyte.
In order to create haploid spermatids, secondary spermatocytes, which are only present for 8 hours total, go through a second meiotic division (meiosis II).
The germ stem cells of the seminiferous epithelium in the testis are known as spermatogonial stem cells (SSCs). Spermatogenesis is the process by which they create sperm while concurrently maintaining a consistent cellular pool through self-renewal.
A tiny subpopulation of spermatogonia, which are cells found in the basement membrane of seminiferous tubules in the testis, which are crucial to the process of spermatogenesis.
The sex organs are covered by a thick layer of cells called the germinal epithelium during the embryo's early developing stage. These cuboidal cells can be seen in the ovary and testes. It covers the seminiferous tubule wall in the testes of males. It protects the ovary's top layer in females.

Hence, option C is the correct answer.

Note: The primary and secondary spermatocytes may makes confusions. A Type B spermatogonium goes through premeiotic DNA replication, which is the final stage of DNA replication before spermatocytes are "born." The cells, which are officially in "prophase I" of the G2 stage of the meiotic cell cycle, are now known as primary spermatocytes.
